- Copy the output or download it as a .json file.
Frequently asked questions
How much space does minifying save?
Typically 10–40% depending on indentation. The tool reports the exact byte counts before and after.
Can minifying break my data?
No, but it makes the file hard to read. Keep a formatted copy if you plan to edit it by hand.
